Anise Hyssop, also called agastache foeniculum in the herbal world, is a perennial herb that grows to 3-4 feet tall in some areas. Grown best in zones 4 through 9, it is easy to grow since it is self seeding. This means you can plant it once and it will grow back again and again.
Growing Anise hyssop is fairly easy. Just plant Anise Hyssop seeds directly into the soil, about a foot apart, just around a week before the last frost in your area. Anise hyssop will thrive in direct sunlight, but since it is fairly tall it is usually grown in the rear of an herb garden.
The flowers of the Anise Hyssop plant bloom from midsummer to fall and are described as a purple-blue or lavender colour and are edible. They have a licorice flavor and scent that many people love. The leaves are toothy edged, spade shaped leaves that look a lot like leaves from plants of the “mint” variety.
